STEAM-DRlER:

SPECIFICATION forming part of Letters Patent N 0. 736,429, dated August18, 1903. Application filed April 9, 1902. Serial No. 102,120. (Nomodel.)

to make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to a new and novel means to dry steam.

The aim of my invention is to provide an ordinary steam-boiler with asimple device by means of whichthe steam may be dried be-" fore enteringthe service-pipe.

In the accompanying drawings I have shown in Figure 1 an elevation ofone of my steaIn-driers. Fig. 2 shows my drier positioned Within thedome of an ordinary steamboiler. Fig. 3 shows a top view of one of theprecipitating-tubes, while Fig. 4 shows an end view disclosing theposition of one of these precipitating-tubes.

The object of my inventionis to provide a device adapted to be placedwithin the dome of an ordinary steam-boiler, so that the-steam inescaping to the service-pipe will encounter a number ofprecipitating-tubes in such a manner that the moisture within the steamwill be condensed upon the service of these precipitating-tubes, so thatthe steam as it finally enters the service-pipe will be dry, or almostso. The waters of condensation collected and gathered upon theprecipitatingtubes are again directed into the boiler, where they areadded to the body of water in the boiler, so that this water iscondensed within the boiler itself instead of within the tubes leadingfrom the boiler, as is usual.

In carryingout the aim of my invention I provide an ordinarysteam-boiler A with the dome B, secured thereto by any suitable means,the'dome B being provided with the usual top 0 and the service-pipe D,leading to the engine or other point where the steampower is to be used.

At a suitable point within the dome I provide the brace-bar E, whichsupports a vertical main drain-tube 2, which tube is provided at asuitable number of points with the extending shoulders 3 in the form ofstub-tubes, freely communicating with vertical main tube 2. This maintube is open-ended and is provided with any suitable number of thesestubtubes 3.

Removably secured to each stub-tube is a preeipitating-tube comprisingthe collar 4, adapted to slip into one of the stub-tubes 3, and thiscollar for the sake of convenience is provided with the ring 5 tostrengthen. the same, and below, extendingfrom this collar 4, is thesemicircular tube 6, which extends forward a suitable distance. Spanningthis lower half-section of tubing 6 is an upper hood 7, which curvesdownward a considerable distance and is positioned above the lowersemicircular tube-section 6, so as to provide the escape-way 0: betweenthese tubesections 6 and 7.

In Fig. 4 is disclosed an end view, and it will be noticed that theupper semicircular tube-section 7 is very much larger than the lowertube-section 6 and is arranged reversely to the latter.Extendingdownward from this upper tube-section 7 are a plurality ofstubtubes 8, which extend downward and end a suitable distance above thebottom of the pipe 6. Any suitable number of these precipitating-tubescomprising the sections 6 and 7 are used, so that the dome B of theboiler is provided with a metallic tree, as it were, the branches ofwhich radiate outward and against which the steam comes in contact inpassing into the service pipe D. Now the Waters of condensation areprecipitated upon and against the tube-sections 6 and 7 and are drainedthrough thetube 6 to the vertical tube 2. Of course a considerableportion of the moisture will drip off of the lower portions of thesetubes 6 and 7 and drop through into the boiler again. This hot water asit flows back is of course utilized and converted into steam again, sothat there is really a saving in fuel, as so much coal is saved as wouldbe required to raise the collected water to the temperature at which itis returned to the steam-boiler.

The device may be inserted into the boiler through a suitable handhold,as all of the precipitatingtubes are removed from the verticaldrain-tube, and this vertical drain-tube 2. In a device of the characterdescribed,the

combination with a main drain-tube, of a plurality ofprecipitating-tubes connected to said main drain-tube and radiatingtherefrom, each of said precipitating-tubes comprisingreversely-arranged substantially semicircular sections, one of saidsections being of larger dimensions than the other section to overlapand inclose the smaller section.

3. In a deviceof the character described,the combination with a maindrain-tube, of a plurality of precipitating-tubes connected to said maindrain -tube and radiating therefrom, each of said precipitating-tubescomprising reversely-arranged substantially semicircular sections, andvertical drain-tubes connected to one of said sections and discharginginto the other section.

4. In a device of the character described, the combination with a maindrain-tube, of a plurality of precipitating-tubes connected to saidmainWdrain-tube and radiating therefrom, each of saidprecipitating-tubes comprising reversely-arranged substantiallysemicircular sections, one of said sections being of larger dimensionsthan the other section to overlap and inclose the smaller section, andvertical drain-tubes connected to one of said sections and discharginginto the other section.

5. The combination with a main drain-tube, of a plurality ofprecipitating-tubes branching from said main tube, eachprecipitatingtube comprising two half-sections,-the upper half-sectionhooding the lower tube-section, and a plurality of vertical drain-tubesprojecting from each hooded section as and for V the purpose set forth.

In testimony whereof I affix my signature Witnesses:
